To all whom itmay concern: 1 v

Be it known that I, HENRY RUPPEL, a

citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Wick-Regulators for Blue Flame Wick-Stoves, of which the following is a specification, reference being had therein to the accompany- 1 mg drawing.

view of Fig. 1, withthe combustion sections omitted. Fig. 3 is a detached perspective view of my improvement. 1

Referring now to the drawings, 1 indicates an outer wick tube; 2the inner wick tube and 3 the wick therebetween. Any suitable form of wick raising device 4 is used for raising and lowering the wick. The upper end of the outer wick tube 1 has an outwardly extending annular L-shaped flange 5, and the upper end of the inner wick tube 2 has an inwardly extending annular L-shaped flange 6. Surmounting the wick tubes are the inner and outer perforated combustion sections 7 and 8.

My present improvement comprises a perforated diaphragm 9, which spans the upper open end of the inner wick tube 2. As here shown, this diaphragm 9 is provided with an annular L-shaped flange 10, which corresponds in shape and is adapted to fit against the L-shaped annular flange 6, as shown in Fig. 1. The outer edge of the L-shaped flange 10 is provided with a plurality of upwardly extending L-shaped prongs 11. The outwardly extending ends 12 of these prongs extend out in the path of travel bythe .wick 3, as shown in Fig. 1, and thus serve to limit the upwardmovement of the wick- As .here shown, this diaphragm 9 is preferably"removable and the means here shown for removably supporting the diaphragm comprises a central rod 13, hav

ing its upper end screw -threaded, as at 14,

which mesh with internal screw-threads on the central portion 15, which is suitably attached to the center of. the diaphragm. This central portion 15 is provided with radially extending arms 16, which have their outer ends '17 turned downward and engaging the outer edge of the diaphragm. This construction serves to strengthen the. diaphragm and tofirmly hold itsouter edge in shape and in proper position in relation to the flange 6, and prevents the diaphragm frombeing warped or deflected out of shape by the heat from the flame. f

I. am awareit is-old to provide the perfo rated diaphragm with an annular bead with which the wick engages and which is supposed to limit the: upward movement. of the wick, an annular flange, however, to be effective in limiting the wick must practically coverthe top ofthe wick, and this is very objectionable in this type of burner. By providing prongs, as here shown, such a small portion of the top of the wick is covered that it does not affect the operation of the burner, and, furthermore, it presents the top edge of the wick for lighting purposes. The top of the wick is much easier lighted than its outer surface where its top is covered. Furthermore, by the use of prongs the vapor evolved from the inner surface of the wick flows practically as freely upward between the combustion sections as the vapor escaping from the outer side of the wick. In this type of burner it is essential that the vapor evolved from both sides of the wick should unobstructively flow upwardly between the perforated combustion sectionsin order to provide a proper and maximum flame at the top of the combustion sections.

By having the prongs of the particular shape hereshown, the L-shaped flange 10 can be made to fit against the L-shaped flange 6, and thus support the lower edge of the inner combustion section insubstantially the same horizontal plane as the outer section is supported, and yet have the flanges 5 and 6 inthe same horizontal plane. This scribed, the combination with the wick tubes, wick and combustion sections, of a diaphragm at the upper end of the wick tubes, said diaphragm" having radial arms projecting outward over the path of travel of the wick', for the purpose described.

2'. In a: blue-flame burner of the type described, the combination with the wick tubes, wick and combustion sections, of a diaphragm spanning the open upper end of the inner wick tube, said diaphragm having an L-shaped annular flange, the outer edge of the flange provided with upwardly and outwardly projecting wick engaging prongs, for the purpose described.

3. In a blue-flame burner of the type described, the combination with the wick tubes and combustion sections, of a perforated diaphragm spanning the upper end of the inner wick tube, said diaphragm provided with prongs projecting radially in the path of the wick, a central hub-portion and radial extending .arm's engaging the outer edges ofthe top of the diaphragm, all combined for the purpose described.

4;- In' a blue flame wick stove, the combination with wick tubes, and superimposed perforated combustion sections to produce a blue flame, of a wick stop comprising rad1al arms supported at pomts below one of said perforated combustion sections and projecting into the path of travel of the -wick at points above the tops of the wick j tubes to limit the upward movement of the wick, j

5; Ina blue flame wick stove, the combination with wick tubes and superimposed perforated combustion sections to produce a blue flame, of a wick stop comprising radial arms supported at points below one of said perforated combustion sections, and

extending upward and then horizontally into the path of travel of the wick to limit the upward movement of the wick at a point above the tops of the wick tubes.

6. In a blue flame stove, the combination with wick tubes and superimposed perforated combustion sections to produce a blue flame, of a wick-stop, comprising a vertically extending portion having at its up- :per end an arm projecting laterally in the path of the .wick and its lower end connected to a support in a horizontal plane with the upper end of the wick-tube, and

1 extending under the lower end of one of the perforated combustion sections, for the purpose described.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
